FuseBox - RTAMB40BD - 40A Type B 30mA Type A RCBO 1P+N 6kA

The FuseBox RTAMB40BD is a 40A Type B RCBO designed to provide combined overcurrent and residual current protection within a single compact unit for modern electrical installations. This 1P+N device integrates both MCB and RCD functionality, helping to protect circuits against overload, short circuit and earth leakage faults within consumer units. With a 30mA Type A sensitivity, it is suitable for detecting both AC and pulsating DC residual currents, making it appropriate for circuits supplying modern electrical equipment. The single module design supports efficient use of space within distribution boards, allowing multiple circuits to be protected without increasing enclosure size. Its bidirectional capability enables flexible installation, allowing supply to be connected from either the top or bottom terminals to suit site wiring requirements. Designed for use in residential, commercial and light industrial environments, the unit provides a 6kA short circuit breaking capacity for reliable fault protection. DIN rail mounting ensures straightforward installation, while the compact format supports neat and organised consumer unit layouts. This RCBO provides a practical and dependable solution for installers requiring efficient circuit protection combined with space saving design.
